What is email warmup?
Email warm up is a method of getting a good reputation for your email address to ensure your emails make it through spam filters and your address doesn’t get added to an email blacklist.
Many email providers will treat a brand new email address as potentially suspicious until it gets a reputation – to build that reputation, it’s important to only send a small amount of email at a time. Once you have done this for a while, you can start to slowly send more and more as your email gets warmed up.
